A $350 million gas gathering and processing system began its start-up sequence at the end of September, flowing wet gas from Gulf of Mexico producers offshore Louisiana to processing and marketing onshore. The Discovery project marks the first major grassroots offshore gathering and processing system along the Louisiana Gulf Coast in more than a decade. The system is fed by a new 105-mile, 30-in. main line that reaches the edge of the Outer Continental Shelf at Ewing Bank 873 and brings raw gas ashore to a cryogenic gas-processing plant near Larose, La., 35 miles south of New Orleans. With ultimate capacity of 900 MMcfd and a maximum water depth of 785 ft, Discovery`s line ranks as the deepest 30-in. (or larger) line in the gulf. An expansion scheduled for 1999 will extend the pipeline system farther offshore, accessing deepwater wells (3,200 ft deep) at Green Canyon 254. The paper discusses ownership, development, the pipeline, processing, fractionation, and construction.
